Lario Energy, on the base of its know-how, coming from more than 30 years of experience in design and realization of hundreds of air handling systems and steam systems for every kind and dimensions of paper machines, has developed an innovative and powerful automation and control system.
This system comes from a rising enquiry from final users of simplicity, efficiency and precision in managing steam and condensate system: modern systems in fact, are equipped with an increasing number of control loops, in order to assure flexibility and adaptation to the production.
In particular, new drying sections, equipped with fixed siphons, need a marked subdivision of drying cylinders to assure the correct control of condensing charge, which has remarkable variation from drying cylinder to another one. This configuration of drying section needs a drastic increase of control loops of steam and condensate system.
Lario Energy supplies and starts DCS – PCS systems, complete of software specialized for managing of steam and condensate systems and air handling systems, able to eliminate all well-known problems in managing and control.
Electric control boards for our systems are designed and realized completely inside our workshop. This allows a perfect integration, avoiding transmission, of information and technical details, often expensive and problematic.
The realization of electrical lay out inside our technical department and of control boards inside our workshop, allows the best control of quality and careful working test of components: so we avoid to have to do them during start up on site.
To offer to our customers a simple, safe and cheap automation system, Lario Energy has done an accurate market research, bringing us to select two hardware systems on which we have developed dedicated software.
Management of steam and condensate system is based on a video page for selection of drying curves, where curve grade is correlated with the increase of pressure and temperature values of drying cylinders.
The operator has additional video pages available, thanks to them it is possible to value in real time regulating limits of each single drying group, on the base of pressure value of the main group and vacuum value on the first separator vessel.
Anyway, conventional control of every control loop is always possible, thanks to video pages with dynamic synoptic schemes.
Lario Energy dedicated control system allows to set the starting drying curve and to prevent dangerous events like paper peeling, bubbles, compact stratifications of surface, excessive adherence.
Furthermore, a good control in the first part of drying section is really important to avoid paper break.
Our control systems have the required flexibility to heat paper properly and gradually in this part of drying section.
Thanks to pre-set temperature ramps, the control of paper break conditions is completely done automatically.
